Everyone, watch out: Abby Lee’s back on “Dance Moms.” The hard-driving, hoarse, vitriolic Pittsburgh-based dance instructor screams at kids and then she screams at their mothers as she whips little ballerinas into shape. The new season begins with a casting call — may be for more than one dancer — that the girls who have already registered with Lee have to join. The moms try to be understanding but they gossip about the corpulent Lee, who shrieks at one person after another. The girls look victimized, but they like wearing lipstick.

Banjo bacchanalia

New Jersey was never the same after “Jersey Shore.” Wonder what will become of West Virginia, the setting of MTV’s new wanton youth opera, “Buckwild.” A gaggle of rowdy boys and “carefree” girls gather in Sissonville, W. Va., to do what kids do: booze, brawl and well, you know. We’ll meet Shain, high school prom king; Anna, a rich girl slumming it with the lowlifes; Ashley (above right, with Cara), a tomboy; Shae, a spicy Southern belle and Shain’s best friend, Joey. Who is the next Snooki? The next Situation? The next J Woww? You can while away your winter hours figuring it out.

Cuckoo’s nest

Who is the next person to go crazy on “Two and a Half Men,” the Chuck Lorre sitcom? Will it be Jon Cryer (left), who may have been the only “normal” person on the show all these years? Will it be Ashton Kutcher (right), recruited from the ashes of his film career to play shaggy entrepreneur Walden Schmidt? Or will it be Conchata Ferrell, who plays the long-suffering sarcastic housekeeper? The rest of the season should be interesting as Alan (Cryer) uses Walden’s money to invest in a fashion line. They say Angus T. Jones still has a job on this show. Let’s see if he shows up this week. Also with Holland Taylor.
